Jefferson County High School Lesson Plan Friction Teacher: Jessica Minton Grade/Subject: 9th grade/Physical Science Unit: Forces Lesson Title: The Force of Friction Identify what you want to teach. Reference State, Common Core, ACT College STATE STANDARD(S) Readiness Standards, and/or State Competencies. TN Physical Science Standards: Standard 3: Motion Conceptual Strand 3: Objects move in ways that can be observed, described, predicted, and measured. CLE 3203.3.2: Investigate and apply Newton’s three laws of motion. SPI 3202.3.2: Relate inertia, force, or action-reaction force to Newton’s three laws of motion. SPI 3202.3.3: Distinguish among the concepts inherent in Newton’s three laws of motion. LESSON OBJECTIVE Clear, Specific, and Measurable – NOT ACTIVITIES Student-Friendly: "The student will…" Explicitly Stated for Students The students will define friction. The students will distinguish between the three types of friction. The students will apply the three types of friction while observing the effects on several materials. ASSESSMENT/EVALUATION Measures Student Mastery In More Than Two Ways Aligned with the Lesson Objective Includes Measurable Formative and Summative Assessments Requires Written Task Students will be given a summative assessment at the end of the unit to collect data on understanding of the knowledge. Students will be formatively assessed through the Question of the Day (Q.O.D.) over the previous material. Students will be formatively assessed through the set-up and accuracy of their graphic organizer over the three types of friction. Students will be formatively assessed through the mini-lab comparing friction. Students will be orally assessed when asked to list several ways to increase the friction between tires and ice. MATERIALS Aligned with the Lesson Objective Rigorous & Relevant Microsoft PowerPoint Slides LCD Projector/Board White Paper for Graphic Organizer Student’s Q.O.D. pages/Paper for Mini lab data recording Textbook Ice cubes Rocks Erasers Wood blocks Aluminum foil Metal/plastic tray Metric ruler ACTIVATING STRATEGY Hook Essential Higher Order Question(s) Activates Prior Knowledge Real-World Connections There is a Question of the Day (Q.O.D.) that will be on the board as soon as the students come in the door. Their question: If you push a skateboard with your hand does the skateboard keep moving at a constant speed after it leaves your hand? What force is acting on the skateboard that is causes it to slow down? What would happen if I stood on the skateboard and had someone push, would that affect the distance the skateboard would be able to travel? I will have a skateboard in the class that we will experiment with as soon as they finish writing their answers down. INSTRUCTIONAL PLAN 1. 2. 3. 4. 5. 6. 7. Step-by-Step Procedures and Times Modeling Strategy – “I Do” Planned Questioning (Knowledge/Comprehension, Application/Analysis, Creation/Evaluation) Multiple Thinking and Problem Solving Strategies Grouping Strategies Differentiated Instructional Strategies to Provide Intervention & Extension Question of the Day: If you push a skateboard with your hand does the skateboard keep moving at a constant speed after it leaves your hand? What force is acting on the skateboard that is causes it to slow down? What would happen if I stood on the skateboard and had someone push, would that affect the distance the skateboard would be able to travel? (5 minutes) Discussion of the Question of the day and skateboard demo. (5 minutes) Introduction of Friction and set-up of graphic organizer for notes. (2-5 minutes) Notes on Friction on the graphic organizer (15 minutes). Mini Lab on Comparing Friction: pg 71 in the textbook (copies will be made for the students). (15 minutes) Oral assessment/Exit Ticket end of class: List at least 3 ways to increase the friction between tires and ice. (5 minutes) I will be walking around the room guiding the students and to be available for any questions/problems that might arise. (full class time) GUIDED & INDEPENDENT PRACTICE “We Do”-“You Do” Student Work Encourages Higher Order Thinking & Problem Solving Relevance to Students’ Lives Differentiated Strategies for Practice to Provide Intervention & Extension Students will be working on a graphic organizer to distinguish between static, sliding, and rolling friction. After they complete the information, they will be using what they learned to do a mini lab comparing friction. They will be using common objects to test friction at different height levels. They will be using the following questions to help with the lab: 1. List the height at which each object slid off the tray. 2. Why did the objects slide off at different heights? 3. What type of friction acted on each object? CLOSURE Reflection/Wrap-Up Summarizing, Reflecting, Restating, Connecting Provides for Student Engagement Before the end of class, after the mini-lab is completed I will wrap up the class by assessing their knowledge over friction asking them to answer the following: List at least 3 ways to increase the friction between tires and ice. The following could be possible answers: put chains on tires, make tires with steel grips, add sand or some other abrasive to ice, or add weight to the car. This will connect to real world scenarios because some of the students are starting to get their driver’s licenses.
